FIG. 1 is a rear perspective view of a breast pump showing our new design;

FIG. 2 is a front elevational view of the breast pump shown in FIG. 1;

FIG. 3 is a rear elevational view of the breast pump shown in FIG. 1;

FIG. 4 is a left side elevational view of the breast pump shown in FIG. 1, the right side being a mirror image of the left side; and,

FIG. 5 is a top plan view of a breast pump shown in FIG. 1.

The broken line showing of the funnel and bottle in the FIGS. 1 through 5 is for illustrative purposes only and forms no part of our claimed design. The bottom of the breast pump is not visible in its normal or intended use. Therefore, the bottom view is not a matter or ornamental concern, and has been omitted from the drawings.
